Problem with POST on site secured with SSO ?

cholo · **Joined:** Fri Nov 07, 2008 3:24 am **Posts:** 2

Hello,
I'm using full 5.1.1 ActiveX version of control.
My Tomcat application is secured with SSO (CAS) and after successfull login 'JSESSIONID' cookie is set.
The problem is when I try to call 'HTTPUploadThroughPost' method redirection to SSO is returned to the client (read from 'HTTPPostResponseString').
I've tried to add JSESSIONID parameter with 'SetHTTPFormField' but it doesn't work.

Is there any way to set session cookie to be send with POST upload or maybe I can get the content of scanned object in form of PDF, JPG etc. and upload it myself with 'Msxml2.ServerXMLHTTP' object where cookie can be set.

Greetings,
cholo

Would you please send the screenshot of the message returned by the HTTPPostResponseString to twainsupport@dynamsoft.com? I will check it for you.

Would you please be more specific about "it doesn't work"? Do you get any error message when using the method? You can use the ErrorString property to get the error message. For information about this, please refer to:

The field name of the uploaded image is RemoteFile. You can get the content of scanned image form RemoteFile. For more information about this, please refer to:

Thanks.

there is no specific error message.
just plain html content of my login page with user and password fields.

content of login page is returned as before
error string is 'HTTP process error'

'RemoteFile' holds scanned object at the server side but I need to access scanned image as PDF at the client side (from the javascript hosted inside browser page)

Another solution (in case cookie is not supported) is to include 'jsessionid' in call url.
So when I open 'saveScan.jsp' page using fresh browser with url where session id (present at the tomcat server) is set in following form:

Code:

.../saveScan.jsp;jsessionid=C722AB591ECD786914D8E02A74488548

it works (no login page required)
but adding ';jsessionid=...' at the end of 'sActionPage' param in method call

Code:

gScannerObject.HTTPUploadAllThroughPostAsPDF(sHost, sActionPage, sFileName);

does not

Is there any solution for this problem? I am facing the same problem! and this is my code:

Code:

function doUpload(){
   var objScan = frmScan.objScan;
   if(objScan != null){
      var ext = $('#fileType').val();
      var fileName = ($.trim(frmScan.FileName.value) || 'Documents') +'.'+ ext;
      
      var currentPathName = unescape(location.pathname);   // get current PathName in plain ASCII   
      var currentPath = currentPathName.substring(0, currentPathName.lastIndexOf("/") + 1);
      var url = currentPath + 'ScanAttachDocTest?DBName=${DBName}&TableName=${TableName}&Code=${UniqueKeyValue}';
      url += '&FileName=' + encodeURIComponent(fileName);
      alert(url);
      if(ext == 'pdf'){
         objScan.HTTPUploadAllThroughPostAsPDF(window.location.hostname, url, escape(fileName));
      } else {
         objScan.HTTPUploadAllThroughPostAsMultiPageTIFF(window.location.hostname, url, escape(fileName));
      }

      if (objScan.ErrorCode != 0) {//Failed to upload image
         alert(objScan.ErrorString);
         if(objScan.ErrorString == "HTTP process error")
            alert(objScan.HTTPPostResponseString);
      } else {
         if (window.parent.frames.frmThumbnails) {
            window.parent.frames.frmThumbnails.location = window.parent.frames.frmThumbnails.location
         }
      }
   }
}

Hi basheerb,

Would you please let me know which version of Dynamic Web TWAIN you are using? To troubleshoot the problem, you can first take a look at the following article.
http://kb.dynamsoft.com/questions/559/W ... loading%3F

Besides the tips mentioned in the article, you can also use the SetHTTPFormField method to pass the info along with the HTTP Post method.

To download the SetHTTPFormField sample code, you can follow the steps in the article:
http://kb.dynamsoft.com/questions/543/H ... b+TWAIN%3F

FYI, the latest version of Dynamic Web TWAIN is 6.2. If you are using an old version, I recommend you upgrade the control to the latest version.

If the problem persists, you can contact our support team via Live Help to have an online meeting.
